Can anyone come up with an explanation for this as to why someone higher on the D1 list has a lower priority than on the C + list?
Two days ago these folks were on the complimentary upgrade list with me for the D1 cabin from SFO>JFK...I've only listed people listed for both cabins:
Initials...D1...C +
FAB/M...#2...#1
QIU/L...#9...#2
DAV/T...#11...#3
HAL/M...#8...#4
RIC/L...#13...#5
RIC/C...#12...#6
STO/T...#14...#7
CHI/A...#7...#8
PAS/D...#17...#9
HOL/M...#18...#10
FIS/T...#19...#11
MAT/A...#20...#12
DAN?C...#21...#13
SHE/D...#22...#14
JOH/D...#23...#15
RIL/M...#25...#16
MAU/M...#26...#17
ALM/J...#28...#18
SAL/E...#24...#19
PAR/L...#29...#20
CAR/R...#30...#21
So my question again is what would cause the following people to be in a different priority order for D1 vs C +, meaning one is above the other on the D1 list but lower on the C + list?

Using a RUC or GUC puts the person higher on the D1 upgrade list, but these instruments don't apply to C+ upgrades. This would seem to explain everyone on your bottom list except for CHI/A (#7 for C+ but #8 for D1), where my guess would be that someone was already upgraded to C+ and ranked above CHI/A for D1.
I'm not sure how refusing a middle C+ seat (by requesting aisle or window only) would affect the upgrade list--I would assume not at all--but it can explain why a C+ "upgrade" sometimes seems to be given to someone who is lower on the list while skipping over people who appear at the top of the list.
It looks like a lot of passengers attempted to use GUCs/RUCs for this flight, which isn't surprising for SFO-JFK.

Earned DM with reserve plus minimum hit for plat next year. Was 1 of 53 using RUC for JFK to LAX, started the day with 5 seats and zero at the gate. Not sure if I was leapfrogged by a GUC or just confirmed D1 from earlier flights chosing to SDC.

On tonight's flight from SFO to JFK there are 2 D1 "Seats Remaining" on the Upgrade & Standby screen but if you try to book a seat the flight (including D1) is sold out. Does that mean D1 is sold out and those 2 seats remaining are yet to be assigned to people with D1 tickets, or are there actually 2 seats remaining that will go to people on the upgrade list (assuming it stays that way until boarding)?

That's my guess, too. I'm #1 on the D1 list (still showing 2 available) and C+ list (showing 1 available), so we'll see what happens. I'll report back!

Even if the final two do check in, there's a decent chance of a no show, SDC to another flight, missed flight/connection, etc. You might want to consider not boarding when D1/DM is called, especially if you're not desperate for overhead bin space.

Hi, as a new GM can someone explain how upgrades work at the gate? I have two trips scheduled this month. I understand that within 3 days I might be notified (and right now some of the flights have a lot of empty seats listed in the upgrade record). But how does it work at the gate? Do I need to do anything? My record shows I want to be upgraded to C+ or first. Thank you.

Just bought a last minute flight ATL-SLC on 763. Only middle seats in economy left, so I did not select a seat, figuring I have a better chance of the gate agent or system auto-assigning to a blocked seat, and cant do any worse than options left. However, if you dont have seat assignment, will there be any negative effect on comp upgrades? I assume system will upgrade into c+/F regardless of whether there is a seat assignment in Y, but Ive never actually tested.

Also, you'd be surprised how much movement there seems to be in seat assignments, especially as departure approaches, presumably due to upgrades and SDCs. (Check especially right after the DM/PM and GM windows open for upgrades, and also after T-24 when people become eligible to SDC to a different flight.) If you keep stalking your seat maps, chances are very good that a seat you like will become available.

Have a trip tomorrow and as a PM, I am not showing up on the upgrade lists. My trip details show upgrade requested for both legs but when looking at the upgrade list, I am not on it. First time I have noticed this, any ideas as to why?

If you haven't checked in yet, then the answer is much simpler

Have a flight tomorrow where a 20 seat F cabin is mostly empty yet appears no upgrades have been processed. Its the 2nd segment of my trip and DL isn't even offering a paid upgrade... yet the direct flight they are. Pretty crappy.
Am wondering if this segment is going to be glitched once I'm able to check in and not be on the upgrade list. Tried removing and re-adding the upgrade request but not sure if that will fix anything.
